Mani Haghighi is the latest to be impacted, the actor and director having been prevented from leaving Iran to attend the BFI London Film Festival, where his film Subtraction was due to premiere on Oct. 15. The Hollywood Reporter understands that Haghighi, who first debuted the film in Toronto, where he was able to attend, was stopped at the airport in Iran and had his passport confiscated. He has since returned to his home in Tehran.
